Avoid using a telephone during a thunderstorm. There might be a slight chance of electric

associated with the closing of any electrical circuit. In an inadequately ventilated environment, 
the user should not plug the phone into a power outlet, nor put a charged handset into the 
cradle where there are concentrations of ammable or ame-supporting gases. A spark 
in such an environment could create a re or explosion. Such environments might include: 
medical use of oxygen without adequate ventilation; industrial gases (cleaning solvents; 
gasoline vapors; etc.); a leak of natural gas; etc.
